IMPROVEMENT IN SNOW-GUARDS FOR ROOFS.

Specification forming part of Letters Patent No. 190,204, dated May 1,1877; application filed April 9, 1877.

To all whom it may concern Be it known that I, GEORGE F. FoLsoM, ofBoston Highlands, in the county of Suffolk and State of Massachusetts,have invented a new and Improved Snow-Guard for Roofs, of which thefollowing is a specification Figure 1 is a side elevation of my improvedsnow-guard. Fig. 2 is a plan view. Fi 3 is a front elevation.

' Similar letters of reference indicate corresponding parts.

My invention consists of a right-angled or L-shaped strip of sheet metalthat isfolded to form a square face, a brace for holding the same, andwings which pass under the slate for supporting the brace.

In addition to these features, the square face is slit up for a shortdistance each side of the brace to form prongs,

' that spring against the surface of the slate,

and, in conjunction with the wings, clamp the slate, so that the guardwill not slip from it. The object of the invention is to provide asnow-guard for roofs that may at any time be attached to the same, andthat will eifectually prevent the snow from sliding bodily from theroof. 1

In carrying out my invention I take an L- I shaped strip of metal, cutat right angles, havin g a suitable Width, and arms of equal length,and, by aid of suitable to ols,I bend it on a line formed by thecontinuation of the line of the inner edges of the arms of the strip, soas to form a square surface, A. I then fold down the arms of thesheet-metal strip to a diagonal line, a b, and from this point backwardon a line at right angles to thei'ace of the square A, and in contactwith each other, forming the brace B. I then spread the ends out,forming the Wings O, the plane of which is at right angles to that ofthe brace, and also the square A. The square A is slit upward for ashort distance from its lower corner at each side of the brace B,forming prongs c, which, in conjunction with the wings O, clamp the Islate as the guard is placed in its position on the roof.

Having thus described my invention, I claim as new and desire to secureby Letters Pat- 611t As an improved article of manufacture, a snow-guardfor roofs, consisting ofan L- shaped strip of sheet metal, having twoequal arms. the same being bent to form the square A, brace B, wings O,and slit to form prongs c, all as herein shown and described.

GEORGE FRANKLIN FOLSOM.
